TABULATING DEVICE FOR TYPE-WRITING MACHINES.

I SPECIFICATION forming part of Letters Patent No. 767,838, dated August16, 1904.

Application filed March 21, 1902. Renewed April 21, 1904. Serial No.204,284. (No model.)

To all whom, it may concern:

Be it known that I, JEROME B. SEooR, a citizen of the United States,residing at Derby, in the county of New Haven and State of Connecticut,have invented certain new and useful Improvements in Tabulating Devicesfor Type-VVriting Machines, of which the following is a specification.

This invention relates to improvements in tabulating devices fortype-writing machines; and its object is to facilitate the tabulatingoperation by providing column-stop devices .which can be instantly setto operate at any given column without necessity of careful adjustmentby the operator.

With the usual tabulatingdevices it is necessary when a column is to bewritten in a definite part of a page to carefully adjust an adjustablestop to the required point. This requires time and care, and the removalof the stop to one side when tabulation is no longer desired also takesan appreciable time.

My present invention comprises the provision of column-stops that arenot adjustable that is, are not movable longitudinally of thecarriage-but may be moved laterally with respect to the carriage tobring them into or out of cooperative relation with the tabulating-keydevice. Said tabulating-key device may have a single stop-key or aplurality of keys to give a decimal or denominational stop.

In the accompanying drawings, Figure 1 is an end elevation with partsbroken away of a type-writing machine, illustrating the invention. Fig.2 is a partial rear elevation of the same. Fig. 3 is a detail view of aspring-drum provided with a peripheral graduated stop device, a ashereinafter described.

1 may represent the frame, and 2 the carriage, of any usual or suitableform of typewriter. The column-stop-controlling devices carried by thecarriage consist of shiftable tappet-lugs 4, which in this illustrationare shown as pivoted to swing vertically on the carriage-bar 3, so as tobe brought into or out of cooperating relation with a cam device 10 on abell-crank lever 10, pivoted at 10 to the machine-frame and engaging atits other end with a lever 11, pivoted at its lower end at 11 to themachine-frame and having an arm or lug 11., which extends under a seriesof stop-levers 12, pivoted on a pivot pin or shaft 13. These levers 12are each formed at its end with a projecing nose, as shown in dottedlines in Fig. 2, extending obliquely downward and adapted to engage withstop means 14, formed on the periphery of the usual spring-drum 15,which is geared to the carriage in the usual manner. The stop means onthe spring-drum may, as shown in Fig. 3, consist of oblique slots 14,formed in a band on the outside of said drum and having on their sideswhich engage with the stop-levers 12 steps 15', arranged at angulardistances circumferentially of the spring-drum corresponding with theletter-space feed on the carriage. The distance asunder of the obliqueslots 14 circumferentially of the-drum determines the distance betweencolumns and corresponds with the distance between the tap petlugs 4,which may represent one inch, more or less, in the feed movement of thecarriage. The steps 15 (here shown nine in number) in each slot 14correspond with letter-spaces or decimal value of the figures in eachcolumn. There is one stop-lever 12 for each of the steps 15, and thesestop-levers are severally actuated by separate tabulating-key levers 7,one for each, which bear upwardly against the respective stop-levers 12,either directly, as in the case of the upper three, or through themedium of rods 16, as shown in the second and third sets of three. InFig. 1 dotted lines indicate the terminal ends of the key-levers 7 ineach range which are controlled by the one shown, each successivekey-lever being made slightlyshorter than the one before it, so thateach will actuate one of the stople\ ers 12. In like manner thestop-levers 12 are made of different lengths, so that each willbeengaged by one only of the key-levers. The respective stop-levers 12are formed on their under sides with notches 12, that allow freedownward movement of the lever except when the lever 11 is moved (to theright in Fig. 2) by the bell-crank 10, as aforesaid, when a horizontallug or arm 11 on said lever 11 comes under a projection or shoulder 12on all the levers 12 and prevents depression of said levers. Springs 7serve to return the keylevers 7 to normal position. A release-lever 18is fulcrumed to the fixed frame at 18 and connected to a cross-bar 18,which extends over all the levers 12, so that when any one of saidlevers is moved one end of the said release-lever will be raised and theopposite end will bear down on a pin 19, connected with escape mechanism(not shown) to effect the release of the carriage from the escapement orstep-by-step feeding mechanism, which may be of usual or well-knownform. I prefer to provide means for easing off the shock due to arrestof the spring-drum by the stop-levers 12, and for this purpose I mountthe pivotshaft 13 in a slot-bearing 20 on the fixed frame part in suchmanner that it can slide parallel to the motion of the carriage, and aspring 21 is provided which draws the said shaft toward the spring-drum.

The operation of the device isas follows: Normally all of thestop-controlling devices 4 are in depressed position, as indicated forthe device at the left in Fig. 2, so that in the travel of the carriagethe stop-controlling devices 4 will successively strike and depress thecam device 10 and through the lever 10 will operate the lever 11 andhold the lug or arm 11 thereon under the shoulder 12 of all the levers12, thereby preventing operation of any of the stop-levers 12. If theoperator desires to write in any particular column, he moves thecorresponding column-stop-controlling device 4 to a position wherein itwill be free of the cam device 10, and when in the travel of thecarriage this column-stop comes opposite the cam device 10 said camdevice being free will allow the lever 11 to remain out of cooperativerelation with the shoulder 12" on stop-levers 12, thereby leaving thesaid stoplevers free to be depressed. The lever 11 is restored to normalposition by a suitable spring and by its pressure against the lower endof the bell-crank lever 10 restores this to normal position whenreleased. Assuming that the operator has depressed the propertabulating-key 7 for the denomination he desires to write, thecorresponding stop-lever 12 will fallagainst the spring-drum periphery,and the principal stopping means 14, which is then opposite thestop-levers, will engage with the operated stop-lever 12 by that one ofits respective stops which corresponds to said stop-lever. In suchengagement the arresting of the carriage is not sudden, but is taken upby the spring 21, the carriage being finally arrested by the shaft 13reaching the other end of the pivot-slot 20.

The stop-lugs 4 retain by friction either position in which they areadjusted. The distance to which they may be pulled out into operativeposition beinglimited, theyoffer un yielding resistance to the stop-keydevice used in conjunction therewith.

From the above description it will be apparent that the oscillatingstop-levers 12, operating in conjunction with the oblique sets of teeth-15' on the feed-drum, constitute rotatable denominational stops whichare rotated to bring them to different denominational positions, and thekey-levers 7 constitute means for locating said denominational stops atdifferent denominational positions, also that the adjustable dogs 4,bell-crank levers 10, and levers 11, in combination with the stop-levers12, constitute tabulating-stops cooperating with the denominationalstops, for the reason that the manipulation of the several equidistantadjustable dogs 4 locates the column in which the printing is to bedone.
